Athanasia de Alger Obelia, sole legitimate heir of the Obelian Empire, recalls a past life; through those memories she foresees a future where her own father, Emperor Claude, ends her life. Though he showers his older sister Jennette Margarita with affection, he treats Athanasia with cold indifference, leaving her aching for his approval.
To escape this destiny, the young Athanasia vows to flee the palace when she matures and, meanwhile, steer clear of her father entirely. Yet their paths intersect long before fate intends, placing the tender girl under Claude's capricious influence. Yet the expected indifference never appears on his face. With a father who now regards her as part of the family, Athanasia works to become a proper crown princess—though her bleak prophecy might still find a way to materialize.
